Toall-zbhomitmagc oncern:

Be it known that I, HANs PETER, acitizen of the SwissRepublic, andresident of Liestal, in the Republic of ,Switzerland, have invented newand. useful Improvements in Carbureters for Internal-Combustion En- Igines, of which the following is a full, clear,

and exact specification:

This invention relates to a carbureter for internal combustion enginesand to that class of devices wherein the liquid fuel is supplied bycapillary passages and drawn in by meansof the air supplied forcombustion.

According to the invention the finest pul- "verization of the liquidfuel by means of the.

air current in the induction passage is effected through the medium of abundle of separate elastic, flexible threads, not a wick, which threadsare loosely outstanding at the discharge end and are set into vibrationby the air current at the end at which the liquid is picked ofi, wherebthe liquid threads are by a whip or lash-1i e action pulverized to afine mist and delivered to the "air.

The accompanying drawing shows in sec tional elevation one form ofcarbureter emof which dips into a liquid fuelcontaining compartment of asocket 0 held within a liquid fuel receptacle e. "The combustibleliquid. is supplied to the latter through the lateral inlet 7 from avessel furnished with afloat-feed, and not shown in the drawing,

so that the level of the liquid remains constant in the socket e. Theair necessary for the formation of the combustible mixture enters the,tube a at its lower end and is drawn in a strong current over the u perend of the thread bundle d from whic it picks oil the liquid whichissues from the capillary passages of said bundle and which has beensubdivided into extremely fine threads by the practically arallel,continuous capillary passages whic extend between the threads of thebundle d, the thus pul- Specification of Letters Patent.

verized liquid fuel mixing with the air cur-- rent in the nozzle 6, andfurther liquid risflexible threads, such, for example, as horsehair,which is inserted in the sleeve-like art of the socket e and the upperend of w ich projects freely outstanding andis expanded to a conicalshape by a spraying cone m. The upper free extremities of the threads ofthe bundle, which are-spread out elastically to an oblique position, arevibrated by the air current striking externally upon them andby theirwhip or lash-like action thus set up, pulverize the liquid whichhasrisen through the capillary passages provided between the threads of thebundle. and discharge the thus-pulverized fluid into the air. As will beseen, the arrangement is one which provides at the discharge'end of thebundle d a spreading of the liquid which is favorable to itsdistribution.

The above described device is suitable for use with light and heavyhydrocarbons and in all cases a complete, soot-free combustion isobtained. This may be due mainly to the extremely fine pulverization ofthe com bustible at the discharge end of the thread bundle d.

What I claim is:

1. In a carbureter .for internal combustion engines, an air inductiontube, a liquid fuel container combined therewith and a liquid fuelfeeding bundle of separate, elas-' tic, flexible threads, said bundlebeing so arranged as to have its lower end within saidliquid fuelcontainer and its upper end freely m into said air induction tube, sothat themduced air current may cause the free up er ends of the threadsto vibrate and to t us pulverize the fuel by a whip-like action to finemist delivered to the air, substantially as hereinbefore described.
